6 Signs of a Broken Water Pipe Outside Your House

Q: How much does it cost to repair a broken water line outside a house?

The cost varies depending on the location and depth of the leak, pipe material, accessibility, excavation requirements, permits, and whether landscaping, pavement, or concrete must be restored. A plumber typically needs to locate and inspect the damaged pipe before providing an estimate.

Q: Is a broken exterior water line an emergency?

It may require emergency service if water is rapidly surfacing, the home has lost water service, the ground is sinking, water is approaching your home’s foundation or electrical equipment, or the leak cannot be controlled. Even a smaller suspected leak should be addressed quickly.

Q: Who is responsible for a broken water line outside the house?

Responsibility depends on the location of the break and the rules of the local water provider. The utility may maintain the public portion of the line, while the homeowner may be responsible for the section between the meter and the house. Confirm the responsibility boundary with your local utility.

Q: How can I tell a water-line leak from a sewer-line problem?

A water-line leak is more likely to cause water-meter movement, increased water use, low pressure, or clear water surfacing in the yard. A sewer problem is more likely to cause slow drains, gurgling fixtures, sewage odors, or wastewater backups.

Water gushes from a broken blue outdoor pipe, flooding the surrounding soil and landscaping beside a house.

Signs of a broken water line outside your house may include a higher water bill, unexplained puddles, low water pressure, unusual pipe sounds, a moving water meter when fixtures are off, or discolored water. Turn off all water use and check your meter. If it continues moving, you may have a hidden leak.

6 Signs of an Exterior Water Leak

Here are six signs to watch for that indicate a potential broken water pipe outside the house.

Warning sign	What it may indicate	What to do next
Higher water bill	Water may be escaping from a hidden pipe	Compare recent water use and check the meter
Unexplained puddles	A buried water or irrigation line may be leaking	Turn off the irrigation system and monitor the area
Low water pressure	Water may be escaping before reaching the house	Check whether several fixtures are affected
Hissing or bubbling sounds	Pressurized water may be escaping through a damaged pipe	Listen when fixtures and appliances are off
Moving water meter	Water is still flowing somewhere on the property	Isolate indoor and outdoor water use
Discolored water	There may be pipe corrosion or a water-supply disturbance	Contact your utility or a licensed plumber

1. Higher Than Usual Water Bill

While your water bill may not be the same every month, it probably stays within a specific, predictable range. If you use significantly more water one month than is typical for your household, you’ll probably understand why, but if your water bill suddenly increases for no reason, the culprit may be a leaky pipe or a broken line outside your home.

How to Check Your Water Meter for a Leak

You can use your water meter to check for continuous water flow:
Turn off faucets, appliances, irrigation systems, and other water-using equipment.
Check the meter’s flow indicator or record the current reading.
Wait without using water and check the meter again.
If the indicator moves or the reading changes, you may have a leak.
Turn off the irrigation system separately to help determine whether it is the source.

A moving meter confirms that water is flowing, but it does not target the exact location of the leak. Professional leak detection may be needed.

2. Unexplained Puddles

Unexplained puddles in your yard can be another indication there’s a water pipe leak outside your house. If you notice this, contact a professional plumber right away before more significant damage occurs. Fixing underground pipe leaks requires special equipment most homeowners don’t have.

3. Low Water Pressure

If your indoor or outdoor water pressure seems lower than usual, this could be a cause for concern. A sudden drop in water pressure, especially when using multiple fixtures simultaneously, may suggest a water line break outside your house or a leak in the pipes. The reduced pressure occurs as water escapes through the leak, affecting the flow to your faucets, showers, and other water outlets.

4. Hissing or Bubbling Sounds

Listen closely—unusual sounds emanating from the pipes, such as hissing or bubbling, can also be a red flag. These noises indicate water escaping through a small opening, which may be a broken plumbing pipe. If you hear unusual sounds, it's a good idea to investigate further, as they can lead you to the leak’s location.

5. Frequently Clogged Drains

Frequent drain clogs, especially in outdoor areas like driveways or garden drains, may indicate a water leak. Leaking water can carry soil and debris into the pipes, causing blockages. If you notice persistent drain issues, there’s a possibility of an outdoor pipe leak.

6. Discolored Water

Keep an eye on the color of your water. If the water appears rusty or has an unusual color, it could mean that soil or contaminants are entering the water supply through a break in the pipes. There could be a broken water pipe under your house or a leaky line in your yard. Address this issue quickly to ensure water safety.

What Causes a Water Leak Outside?

There are several reasons that leaks in your outdoor pipes can develop, and many of them are plumbing problems you shouldn’t try to fix by yourself.

Corrosion of Old Pipes

Over time, pipes can corrode due to exposure to the elements, soil conditions, and the quality of the water flowing through them. Corrosion weakens the pipe material, leading to cracks and leaks. Metal pipes, such as those made of iron or steel, are particularly susceptible to corrosion.

Improper Installation or Materials

Improper installation or shoddy workmanship can all lead to problems later on. Pipes that are not correctly joined or sealed are more likely to develop leaks.

Extreme Temperatures

Another possibility is that extreme temperatures have been damaging the pipes over time, especially if you live in an area with harsh winters. When water freezes, it expands and exerts pressure on the pipe walls. This constant pressure will take its toll on even the highest-quality pipes, eventually requiring replacement.

Ground Movement

Shifting soil or ground movement can put stress on underground pipes. This is especially true in regions prone to seismic activity, unstable soil conditions, or construction zones.

High Water Pressure

Excessively high water pressure can strain pipes, causing leaks and other damage. Installing pressure regulators and routinely checking and adjusting water pressure can help prevent leaks caused by excessive force.

Tree Roots

As much as we love our mature trees, their presence near underground pipes can be a sneaky cause of leaks. Tree roots are naturally drawn to sources of water, and they can infiltrate pipes through small cracks or joints. As roots grow and expand, they exert pressure on the pipes, causing them to break and leak.
